Does Time Travel Already Exist? | Unveiled

What If Time Travel Already Exists? Back in 2009, Stephen Hawking threw a party
for time travellers, complete with a buffet, balloons, and chilled champagne. He waited for his guests to arrive, but ultimately
no one came… After all, he’d sent out the invitations
only after he had thrown the party. Hawking saw this as proof that time travel
didn’t exist, but couldn’t deny throughout his career that it may be possible. This is Unveiled and today we’re answering
the extraordinary question; What if time travel already exists? Are you a fiend for facts? Are you constantly curious? Then why not subscribe to Unveiled for more
clips like this one? And ring the bell for more fascinating content! Time travel is one of the most popular modern
sci-fi tropes around, present in series ranging from “Harry Potter” to “Doctor Who”,
“Star Trek” and more. However, the concept of travelling in time
via mechanical means was first popularized more than a century ago in 1895 by HG Wells’
novel “The Time Machine”. Though it may seem like it belongs only in
fiction, however, time travel is scientifically plausible, and in fact, technically does already
exist. That’s because Einstein’s theory of Special
Relativity explains that time is subjective and can speed up or slow down depending on
how fast you’re going. So, if you travel near the speed of light
for five years in your time, decades could have passed back on Earth. Everyone you knew before your trip will have
grown old, even though from your perspective only a few years will’ve passed. So, today’s question, on the face of it,
is very plausible… Time travel (to the future, at least) is an
idea with sound science to back it up. In fact, some astronauts have already time
travelled into the future, but only by the smallest of margins. Russian cosmonaut Gennady Padalka can reasonably
claim to be the world’s most prolific time traveller, as he has spent more time in orbit
around the Earth than anyone else. Because of time dilation, he’s time travelled
around 0.02 seconds into the future during his missions, meaning he’s aged 0.02 seconds
less than everyone else alive. But that’s only time travelling forwards. What about travelling backwards in time? It’s a notoriously tricky concept, and there
are certain paradoxes that come into play… including Bootstrap Theory, which says that
bringing an object back in time means that that object existed before it was created,
and so has no determinable origin; a clear problem. Then there’s the Grandfather Paradox which
posits that if someone were to go back and kill their grandfather, they would prevent
themselves from ever being born, and so would never have been able to go back in time in
the first place; another sizeable issue! However, both of these can be solved if we
assume infinite timelines and universes – allowing for all of the possibilities to unfold. So, if time travel exists, it’s almost certain
that there are also countless timelines to cater for it, with “new realities” forming
every few seconds. In which case, would we ever know that time
travel exists, even if it already does? There’s a chance we might not. If technology is developed that allows us
to travel around the speed of light, to push us into the future, it would have zero effect
on us in the here and now. So, as we live our everyday lives driving
to work, eating lunch, and watching TV, there’s a seemingly distant (though still very real)
possibility that someone else is jetting off in front of you, aging far less rapidly than
you are. That person could theoretically travel to
the year 2100 having only aged a year or two…. But we’d never know about them because we’d
likely never meet them. And if we did meet them, we’d perhaps be
sceptical of their story. But still, via those potentially infinite
universes and timelines, we could all be experiencing the effects of time travellers messing up
our own timelines every day. Say someone travelled back in time to prevent
you getting in a car accident; they’d then split your life into two; one where you crash
in a fatal accident, and another where you don’t. Every time someone spliced your original timeline,
they’d birth new ones right alongside it – and the multiverse becomes an ever-thickening
web of everything that ever was, is or could be. But you, as in the “original you” living
in your “original timeline”, would be completely oblivious and would never know
that time travel existed or that it had shaped your life to this point. On the other hand, if you were living across
one of the other timelines, you might come face-to-face with solid proof of time travel. So, somewhere out there, a different you could
even be time travelling right now – completely aware that you exist even if you’re unaware
that they do. If technology for travelling to the past has
already been invented (after all, if it’s to ever exist, then why not right now?) it’s
likely that world governments would keep it under strict lock and key… as that sort
of tech could cause huge problems. Unless time travel was rigorously regulated,
anyone and everyone could show up in all sorts of time periods, leaving artefacts from the
future, blowing their own cover, and altering human history. Changing even the smallest thing could send
ripples through time all the way up to the moment you yourself first time travelled – which
could be disastrous for the world around you. So, if time travel already exists, then there’s
surely a “time police”, too. It’d be their job to stop others from creating
chaos – like a time travel version of the Men in Black, maybe even erasing your memory
if you’d ever seen anything you weren’t supposed to. More specifically, if time travel really was
real, it could provide answers to some unexplained phenomena in our standard, non-time-travel
lives. It could be that Déjà vu is simply the experience
of having our own timeline split by an unknown time traveller’s actions, leaving us to
feel as though we’ve experienced the same thing twice. The Mandela Effect, causing shared but incorrect
memories, might be another sign. Common examples range from believing that
Curious George has a tail (he doesn’t), to recalling that Nelson Mandela passed away
in prison (he didn’t). If time travel already exists, these false
memories could be down to some kind of glitch caused by an errant traveller’s antics. There’s no doubt, though, that if time travel
does exist, those who know about it and can use it have unrivalled power. They’d have prior access to news stories,
exam questions and lottery numbers (unless the “time police” outlawed it) and, for
as long as they could even glimpse the future, they’d know which companies were best to
invest in. More than money, though, they’d have the
ability to peek through anybody’s life story at any time… and potentially the power to
reshape, redirect, prolong or cut short any life they felt like. Without even knowing it, those not privy to
time travel would be completely under the time travellers’ control. And the scary part? If you accept that time travel’s even theoretically
possible, then all of that should inevitably be happening right now. Because, if time travel is to ever exist,
then surely it already does? Someone, somewhere, at some time should’ve
already mastered it. And that’s what would happen if time travel
already exists. What do you think? Is there anything we missed? Let us know in the comments, check out these

About the author


  1. What If a Time Traveler from the Past Appears? Answers in the video below ->

  2. If time travel exist, it would cost astronomical energy and galaxy-scale fortune, no one would waste it to join a boring party.

  3. Time travel has always exist; the fact is that, we do not understand or we misunderstad the concept, both things perhaps. A hint, to conceive such an idea in our minds, is to think first in terms of singularity; which itself, is an entire subject of study.

  4. If the multiverse theory is true then there is a universe where the DC comics is real and were in the universe where its just fiction

  5. I like that. If time travel will exist in the future then it exists now. So either it exists or it doesn’t. I think it does. Maybe that explains assassinations if important people we never seen coming. That actually seemed strange anyone would want to kill them, unless they did something we never knew about.

  6. One thing you need to remember, they don't use normal signal or power source to travel through time. They maybe use somekind of Time Sphere or idk. This coukd explain for those asking, "if they time traveling, how they getting signal to do call ?".

    When time travel exist, more and more advance technology is possible to be build, don't trap them having the same mind as our scientist have 🤝

  7. Is not anti matter – matter that vibrates backwards? So isn’t anti matter technically time travelling? I’ve watched too many ufo documentaries about 0 point energy lol

  8. Time is thoerheticly man made, and due to the fermi paradox our human civilization will never advance fast or far enough to harness time travel. Therefore it will never be used in a way to help us unfortunately.

  9. Everyone misses the boat because of the assumption that the future is made by and after the past, when in my tempo we know that the past is being made simultaneously with the present and future. What we do in the present and future affect the past, and that is a completely normal concept to us.

  10. Time travel already does, consciousness transcends time because it can perceive the passage from one moment to the next. Time is a constant moving force whipping through the cosmos from the infinite negative to the infinite positive and we are passed over in our brief life in the here and now to in the end be forgotten in the abyss of infinity.

  11. I love Hawking's approach to the time travel question… just throw a party for time travelers by sending out the invites after the party is over. It doesn't disprove time travel because there are any number of reasons time travelers could exist and not show up, but its the most entertaining experiment I've seen to date to try and prove the theory. Just goes to show you that not only was he one of the greatest minds in history, but he also had this whimsical side to him that always showed through in many of his works.

  12. If travel to future your timeline is destroyed because then you come in future you already disturb you past. And if somehow you accurate travel to your timeline it will be changed one way or another. Because if you really time-traveller you will know one thing that travelling to the future is only one way. Because travelling in time it's like jumping from one high way to another high way but true the sort way. SO cars in your past way are mowing too right?  🙂

  13. It doesn't if you go in a time machine you will die your atoms would separate o and the way you explain time travel your really really wrong I've been working on this for a while and trust me your wrong your knowledge is out dated

  14. There is no such thing as the Mandela Effect, it is just stupid people not being able to remember things! How can it ever be proved? The majority of the population believe Mandela didn't die in prison and factual historical evidence says he didn't.And if people had their time line changed, they would not be able to remember it, some women came up with this "Theory "in the 90 's and it has never made any sense to me.

  15. I believe that we can and do send people back in time. However, they can not return to the present or travel into the future.

  16. The bootstrap theory explain will explain how the universe was created and not the bigbang. The universe time travelled back. So it existed before it was even created. The reason why we can't determine the birth of the universe.😁

  17. If there is only one universe than we would have to wait until we discovered time travel however we can assume time travel hasn’t been discovered in any universe due to the fact if multiple timelines exist then surely somebody would have told us about time travel or left a trace humans are pretty clumsy even the biggest geniuses of the world humans make mistakes

  18. Hypothesis: Since many complete objects can occupy the same space at different times, then one complete object can occupy many spaces at different times including a time before it's creation.

  19. If a time machine is ever invented who's to say that the inventor wouldn't take every precaution to make sure his steps weren't followed in order to remain nearly godlike? i mean the scale of power is beyond wanting money. i imagine a time traveler would very quickly realize that they are beyond the need for money and can shape the universe/worldly events to go down how they choose. (nothing is impossible when you essentially have infinite time)

  20. Why would governments from the timelines, where the tech for time travel exists, restrict the use of it since, as you've said, it wouldn't affect the time line where the tech exists?

  21. Memory Recall and deduction are the baby steps of time travel. We live in time loops that allow pridiction. I can peidict on Monday you will be on the train to work. Because you live in a time loop. There is a bit more mastery to travel hundreds or thousands of years into the future. Going into the pasts is easy it called memory. The problem with explaining time travel is that when someone understands what you are saying they get semantically bound into confusion. Fire torch that does not burn your hand… Impossible. The body is the time machine and we travel forward in time every day with memory of the past. We live in a time loop and live each day continously until through deduction we break the cycle by changing our mind. That is baby steps in travelling through time. When you have collective selves in the same time line that is when it gets intresting. The NOW is all future and past stories. If you look hard enough you can find yourself in the past connected to the now. Go far enough into the past and you start to emerge into the future. We currently are in a junction or extinction period of the human race. There is one way through this hour glass moment if you choose wrong you burn if you choose right you rot and then there is the snow man. The aim of the game is to not cremate your body. But to remain in the now in flesh. This way you maintain a soul perspective. Have fun awakening it is a mad ride. Cheers B hope this helps you take the first step

  22. Time Travel Is Absolutely Not Possible Nomatter How Advanced Our Technology Is No Way If You believe Time Travel Is Possible It Means You Watch Too Much Movies Haha Haha.

  23. Time travel doesn’t exist because time on earth is different from time in space. We must match the speed of the universe. We would have to match its speed to understand it the functions of other planets.

  24. Technically im not here untill you notice my comment
    When you notice it, that means i appear at whatever time your watching this
    So that means im a time traveler.. no? K bye

  25. So is there a timeline out there where I have one less strand of hair on my head and that's the only difference????? 🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔

  26. Hmmmm maybe through astral projection and visiting the Akashic Records but we wouldn't be able to alter timelines we would just be able to view what happened.

  27. ….ok…let's both start in to new york….you on motocycle, I'm in a jet…….let's see if time travel exists???

  28. If Avengers Endgame taught me anything. You can’t change the past. It will only create a new time line👌🏻😤👌🏻

  29. ive problably experienced this paraormal event that happened one time i was watching haunting of hill house its A show and my brother was just watching random vids and then a thing happened for just 1 sec time freakin moved back for 1 sec and shiz i was weirdly confused on what just happened and what i was thinking is that reality is an illlusion which sounds i know non believin for some people but this shiz was true so what if

  30. Maybe the UFOs are us in the future that's why they never make contact with us, because they'll mess up the time line.

  31. If time travel machine exist, it will create a chaos to an entire world depending on the person who holds. If there ever be a major phenomenon, even if one person tries to change the past, the fate itself will create the same outcome. Even if you try again and again, you can never change what will happen in the future, you will failed numerously. You can change some minor events but that will make a risk, every actions creates a consequences even if you change the past that will create a higher possibility of risking someone's/your life and you can never escape from that reality. You need to have someone who is a neuroscience graduate who have knowledge on engineering but prepare for the things that you will experience because it will make you crazy, cause you depression or Post-Traumatic Stress Disorder (PTSD) or even worse.

    Never ever invent the time travel machine if you do not want to suffer. You do not really need to invent that thing. If you think that answers everything, then it's up to you…

  32. What if there are parts of the universe and maybe even in our own Galaxy and maybe even our own solar system that has wormholes. Or at least parts of the universe that's expanding much faster than other parts of the universe because of bigger concentrations of dark energy. What if we can locate parts of the universe and send like a spaceship through one of them?

  33. Time travel is a fantasy. But still love the idea. Were better of exploring the quantum realm. As that is the basis of creation.

  34. If time travelers are messing with time lines, then we're all screwed, unless we track down and stop the time traveler before he (or she) can act to travel through time. Stop time traveling scofflaws from traveling through time! Lock them in the Phantom Zone!

  35. WE ALL ARE TIME JUMPING EVERY SECOND! in the vast multiverse! every choice in moment you make sets a new timeline path! endless multi-universe that all co-exist at the same time

  36. Lol! How egotistical would you have to be to think that time travelers have nothing more important to do than to show up to your party?

    "Guys! Did you hear about this party in 1998??? It's by this guy in a wheel chair who thinks he's the center of the universe! No wonder he's in a wheel chair!"

  37. Technically time travel happens the second you use a vehicle to travel. If it takes 45 mins to walk/run… But 10 mins to drive, 2 mins to fly.. that's called traveling in time.. faster allowing you to accomplish more in the time given….

  38. If you traveled back in time, would you also travel back in space? The earth isn't in the same spot it was 10 years ago. If you traveled back in time but not space, you would end up in deep space somewhere.
